The complete list of methods and parameters

Grey denotes parameters described above or below in the table.

Depending on the direction and destination of the call, different subsets of parameters for the same invocation can be used. For example, in case of the invocation of ConnectionStatusEvent, sipLogin, sipPassword, and othe corresponding parameters are passed. In case of an error, the same event ConnectionStatusEvent will have only two parameters: status and info when sending to a client, and status, info, nodeId, sessionId, appKey when sending to the Web-server.

connect

urlServer

This parameter is used by WCS JavaScript API to connect to the server.

appKey

This parameter passes the REST - URL for the given application to WCS. To view and add applications use the command line interface (CLI).

sipRegisterRequired

If this parameter is true, registration on the SIP server is performed by invoking SIP REGISTER. If the parameter is false, registration on the SIP server is not performed. In this case, a web page cannot accept incoming SIP calls, but still can make outgoing calls if the SIP server allows outgoing calls without SIP registration.
